정부는 2000년에 차세대이동통신(IMT-2000) 사업자 선정을 완료하고 2002년부터 서비스를 시작한다는 계획을 발표했다. 차세대이동통신은 통신장비 및 기술규격의 국가별 차이가 줄어들고 기존의 국내, 국제, 유선, 무선전화, 위성통신, 인터넷, 고속 테이타 송수신 등 모든 현존 신규통신수단을 하나로 통합하는 혁명적 신기술로 사업권을 따내려는 업체들간의 경쟁 및 기존 통신업체들간의 경쟁이 치열해질 전망이다. 정부는 2000년 6월까지 차세대이동통신 면허발급 숫자와 사업자 선정방식을 발표할 계획을 가지고 있다. 정부는 아직 어떤 방식으로 차세대 이동통신 사업자를 선정하고 전파대역을 할당할지 확정하지 못하고 있으나 경매에 의한 주파수 할당제를 도입할 것을 검토중이다. 지금까지 정부의 전파자원 배분은 뚜렷한 원칙이 없고 그때그때 필요에 따라 정하였다. 최근에는 면허제를 채택하여 신청자들의 기술능력, 자금능력 등을 심사하여 전파자원을 할당하는 방식을 써왔다. 그러나 이와 같은 자원배분 방식은 중복투자와 과잉경쟁으로 이어져 무선통신 서비스의 비용상승과 품질저하를 초래하고 있다는 비난을 받고 있다. 전파자원의 효율적 이용을 위해서는 기존의 기술심사에 의한 면허제보다는 경제원리에 입각하여 가장 높은 자원사용료를 지불할 수 있는 사업자에게 주파수자원이 배정되도록 하는 것이 바람직하다.

Capacitive deionization(CDI) is an ion removal technology that employs the basic electrochemical principle of absorbing ions in high surface area electrode. CDI technology reduce power consumption because it operates at lower electrode potential(about 1~2 V). Also, it is an environmentally friendly technology because no acid, base, or salts are required to generate the surface. In this study, we searched the patents and papers to investigate the trend of CDI technologies. Database was collected from WIPS and Scopus site and was investigated according to electrode, module and application technology of CDI. The technology trend of CDI was analyzed based on patent application year, countries, main applications and technologies.

to apply standardized principles and methodologies to the appraisal of records because it is different for each country, region, and organization to distinguish what kind of records are important and how to select them. For this reason, numerous theories and methodologies have been proposed around the appraisal of records. ISO 15489-1:2016, on the other hand, has laid the groundwork for the standardization of the appraisal of records that are applicable globally in recent record management environments based on a new perspective on the appraisal of records. ISO 15489 presents the principles and methodology of records management that are consistent with the electronic record environment based on the record continuum theory, and the principles and methods on the appraisal of records presented in ISO 15489-1:2016 need to be analyzed in depth. This paper analyzes the concept and the logic of the appraisal of records presented in ISO 15489-1:2016 to find an improvement direction in accordance with the recent electronic record environment. For this purpose, it reviewed courses from the enactment of AS 4390 to the revision of ISO 15489 to understand the background of the appraisal principles of ISO 15489-1:2016. Based on this, the appraisal concepts and principles presented in ISO 15489-1:2016 were examined, and the process of the appraisal was analyzed.

Going beyond the previous formulations of development theories, the present paper explores the effects other than political economy on quality of life in a rapidly developing country. The major analysis takes up the historical trend and nature of the developmental transformation that is partially a consequences of state structures and partially autonomous form it in South Korea. Also, it diagnoses developmental pathways for the future track by constructing a baseline model for state transition on the basis of power game between the state and civil society in the country. The results of the historical analysis show that civil society has been transformed in the course of confrontations and interactions between the state and nationalist social movement. The distinction between developmental(or bureaucratic authoritarian) and democratic state is presented to show that these are two qualitatively different aspects of state of state power, requiring separate analytical treatment. Furthermore, the state-centric approach which emphasizes the active role of the state at the sacrifice of societal fabric-constraining social conditions for quality of life - appears to be modified. On the contrary, the impact of civil society is transmitted both directly and indirectly via labor and ecological movement for quality of life, which is critical to the formation of the welfare state in the country. The prospect for sustainable development in Korea lies in providng and expanding quality of life in terms of the financial feasibility of the state through the public-private cooperation, and abstaining from drastic and radical commitment to welfare services as is the case with the European declines in welfare state, Further studies are needed to examine the interrelationships in different historical and cultural settings of developing counties to estimate a theory of quality of life and social justice.

So many nationwide drinking water treatment plants are under much difficulties by new reinforced discharged effluent standards. Generally, the sludge at thickener should be retended for a long time during usual days. Sometime, the soluble manganese and chloroform may be formed under the anaerobic condition in the sludge thickener when the sludge retention time is longer with low turbidity. This phenomenon results in difficulties to keep regulatory level of the discharged effluent. It was necessary to improve the operation conditions and process itself in order to meet water quality standard recently reinforced. For an effort to overcome the problems, a sludge aeration was successfully implemented into the thickening process. Sludge aeration prevent particle oxidated Manganese eluting soluble de-oxidated Manganese, excrete formated Chloroform from effluent to air, and improve sludge settling through homogenized sludge particle. We aerated sludge at the conventional water treatment plant, measured Manganese and Chloroform of clarified water at upper sludge, and solid-fluid interface height of sludge in mass cylinder. As a result, contaminant's concentrations of the final effluent was much decreased : 41% of manganese, approximately 62% of chloroform and 35% of sludge volume, compared with non-aeration sludge.

Last year, the Moon Jae-In administration made an attempt to abolish the presidential security office overseeing the presidential security and to transfer the work to the presidential security service under the National Police Agency. Currently, all of the G7 nations maintain a security system spearheaded by the police, so the policy of transferring the presidential security to the National Police Agency may be discussed. However, it is necessary to focus on the following reality. First, the current presidential security system is consisted of the overlapping security organizations classified into (1) inner ring of the presidential security agency, (2) middle ring of the police agency, and (3) outer ring of the capital defense command. If the presidential security agency is abolished, a vacuum will result as per the principle of class. Second, for the efficient security guard of the President, currently, the presidential security agency at the Presidential Security Safety Measure Committee plays the role of coordinating the tasks. If the National Police Agency becomes the control tower of the presidential security, whether command will be available for the military and diplomatic aspects of the presidential security work should also be considered. Third, Korea is currently in a truce with North Korea, so there is a big difference in terms of the security environment with such G7 nations as the UK, Germany, France, and Japan.
